Abstract

A work machine includes a plurality of actuators and an operation receiving unit for receiving a plurality of operation inputs concerning the plurality of actuators. In a first mode, one actuator among the plurality of actuators operates by one operation input among the plurality of operation inputs. In a second mode, two or more actuators among the plurality of actuators operate by the one operation input. In the second mode, in response to another operation input different from the one operation input among the plurality of operation inputs, an actuator other than the two or more actuators among the plurality of actuators is operated, or a parameter concerning the actuator that operates by the one operation input among the plurality of actuators is adjusted.

Claims (22)

1 . A work machine, comprising:

a lower traveling body;

an upper swiveling body swivelably mounted to the lower traveling body;

an attachment mounted to the upper swiveling body, the attachment including a boom, an arm, and an end attachment;

a plurality of actuators including a swiveling motor configured to drive the upper swiveling body, a boom cylinder configured to drive the boom, an arm cylinder configured to drive the arm, and an end attachment cylinder configured to drive the end attachment; and

an operation receiving unit configured to receive a plurality of operation inputs concerning the plurality of actuators from a first operating lever configured to operate two of the swiveling motor, the boom cylinder, the arm cylinder, or the end attachment cylinder and a second operating lever configured to operate the other two of the swiveling motor, the boom cylinder, the arm cylinder, or the end attachment cylinder,

wherein

the work machine is configured to be controlled in a first mode in which a machine control function is deactivated and in a second mode in which a machine control function is activated, the machine control function being a function of causing one of the plurality of actuators to operate and causing at least another one of the plurality of actuators to automatically operate in response to an operation input for said one of the plurality of actuators,

the first operating lever is operated in a predetermined direction to

cause one of the two of the swiveling motor, the boom cylinder, the arm cylinder, or the end attachment cylinder to operate, when the work machine is controlled in the first mode, and

cause the one of the two of the swiveling motor, the boom cylinder, the arm cylinder, or the end attachment cylinder to operate and cause at least one of the other two of the swiveling motor, the boom cylinder, the arm cylinder, or the end attachment cylinder to automatically operate without an operation of the second operating lever, when the work machine is controlled in the second mode,

the second operating lever is operated in a predetermined direction to

cause one of the other two of the swiveling motor, the boom cylinder, the arm cylinder, or the end attachment cylinder to operate, when the work machine is controlled in the first mode, and

adjust a parameter of said one or the other one of the other two of the swiveling motor, the boom cylinder, the arm cylinder, or the end attachment cylinder or cause the other one of the other two of the swiveling motor, the boom cylinder, the arm cylinder, or the end attachment cylinder to operate, when the work machine is controlled in the second mode,

the first operating lever is configured to operate the arm cylinder and the swiveling motor,

the second operating lever is configured to operate the boom cylinder and the end attachment cylinder,

the attachment includes a bucket as the end attachment, and

the first operating lever is operated in the predetermined direction to cause the arm cylinder to operate and cause the at least one of the boom cylinder or the end attachment cylinder to automatically operate without the operation of the second operating lever such that a predetermined working portion of the bucket moves along a predetermined design plane, when the work machine is controlled in the second mode.

2 . The work machine as claimed in claim 1 , wherein

the parameter includes at least one of an amount of offset from the predetermined design plane, force driving a tip portion of the bucket along the predetermined design plane, a speed of driving the tip portion of the bucket along the design plane, pressing force by the tip portion of the bucket against the design plane, and a parameter concerning an operation of the bucket.

3 . An information processing apparatus for the work machine as set forth in claim 1 , wherein

the information processing apparatus is configured to set the parameter or display set contents of the parameter.
